Description

To provide a seat-type posture correcting device and a chair-type posture correcting device that are used to improve health by allowing a person to naturally adopt a correct posture simply by sitting down when sitting or taking a seat on a chair.

In the past, sitting or sitting on a chair for a long time would cause back pain and fatigue. To solve this problem, many cushions, seat cushions, and chairs have been proposed. Most of the proposed cushions have a certain inclination of the seat surface from the rear to the front, but for example, a chair cushion has been proposed that has a seat surface with an inclination angle of about 10° from one end to the other end in order to eliminate the inconvenience when working or standing up (see Patent Document 1).

Furthermore, a posture-correcting cushion for chairs has been proposed with a specific structure that slopes upward from the rear to the front at an angle of 4 to 8 degrees, with the aim of preventing various health problems caused by poor posture when sitting in a chair, which is caused by the spine curving and putting pressure on the internal organs, and of correcting and improving bad posture by making correct posture a habit (see Patent Document 2).

Furthermore, a triangular posture correction support mat for chairs with an inclination of 8 to 15 degrees in the front-to-back direction has been proposed with the aim of helping users maintain correct posture even when sitting for long periods of time, reducing strain on the lower back, etc., and helping to correct posture (see Patent Document 3).

Although various posture-correcting cushions and chairs as mentioned above are known, they do not give any thought to the gluteal muscles. These cushions and chairs that relax the gluteal muscles cause the pelvis to constantly shake and become unstable, which causes constant stress on the lower lumbar vertebrae and leads to lower back pain. They are uncomfortable and tiring, so they are insufficient in terms of improving posture and improving health.

In addition, when sitting or sitting on a chair, most people are seen to be shortening their gluteal muscles, which leads to poor posture, lower back pain, and poor health.

In order to solve the above-mentioned problems of the conventional art, the present invention aims to provide a seat-type posture correction device and a seat-type posture correction device that allow users to develop the habit of correct posture simply by sitting on it.

In order to achieve the above-mentioned objectives, the seat-type posture correction device of the present invention is equipped with a seat surface that is inclined so that the rear is lower than the front, and the angle of said inclination when seated is within the range of 1.5 degrees to 8 degrees. Since said angle can be maintained even when seated, simply by sitting, the gluteal muscles can be naturally stretched to a moderate degree, stabilizing the pelvis and allowing the spine to be upright, making it possible to form the habit of correct posture.

The chair-type posture correcting device of the present invention is a chair-type posture correcting device that uses the seat-type posture correcting device of the present invention and has a backrest provided behind the seat.

By using the seat-type posture correction device and chair-type posture correction device of this invention, you can make a habit of sitting in a correct posture that moderately stretches the muscles of the buttocks, erects the pelvis, and stabilizes the sacrum, coccyx, and lower lumbar vertebrae just by sitting. The effects of sitting in a way that moderately stretches the muscles of the buttocks and sitting in a way that stabilizes the pelvis (base) will be explained.

If you sit with the muscles in your buttocks stretched and not loosened, your pelvis (base) will be upright and will not wobble, stabilizing your pelvis, sacrum, tailbone, and lower lumbar vertebrae. This will also stabilize your upper spine, allowing you to sit comfortably while driving, reading, and other activities in good posture, and will reduce fatigue. If your buttocks muscles are shortened, your pelvis, sacrum, and tailbone (base of the spine) will undergo various displacements, jumping backwards and causing your lumbar vertebrae to curve forward, resulting in poor posture (spine). Your hipbones will also open and cause bow legs. Bones are pulled by the stronger side of the muscles and displace in various ways, so if you are not in the right posture, you will suffer from lower back pain and various other physical problems (neck pain, shoulder pain, hip joint pain, knee pain, ankle pain, headaches, menstrual pain, irregular menstruation, infertility, constipation, frequent urination, urinary incontinence, fecal incontinence, hemorrhoids, impotence, frigidity, autonomic nervous system imbalance, insomnia, loss of appetite, etc.), and all kinds of illnesses.

Cerebrospinal fluid is a nutrient for the brain and spinal nerves. It is produced in the choroid layer in the center of the brain and protects the brain from external shocks. It also circulates through the brain with the respiratory movement linked to the occipital bone and the sacrum and flows vertically through the gap between the dura mater and spinal cord.
When the sacrum and coccyx are displaced, the breathing movement (the pumping action that normalizes the flow of cerebrospinal fluid) linked with the occipital bone and the sacrum and coccyx cannot be performed smoothly, and when the flow of cerebrospinal fluid is stagnated, the central brain cells and spinal cord cells are severely damaged, and the immune system and healing power decline. In addition, various physical disorders such as autonomic nerve disorders appear, and of course dementia is accelerated and can lead to incurable diseases. In particular, displacement of the sacrum and coccyx (the base of the spine) makes it difficult to get a good night's sleep, which is absolutely essential for maintaining health, and can cause headaches, and it is thought that many of these people also suffer from taste disorders.

Activating the brain generally means ensuring that there is an abundant amount of cerebral blood flow, and to achieve this, good posture (a good spine) is essential. It is of utmost importance that cerebrospinal fluid flows smoothly to activate brain and spinal cord cells. Cerebrospinal fluid can be compared to a power source or a battery. If these cells become weak, all tissues will cease to function.

People are either standing or sitting except when sleeping, but most people spend half of their daytime hours sitting. When sitting in a way that relaxes the muscles in the buttocks, the pelvis (base) becomes unstable, and the joints and intervertebral discs between lumbar vertebrae 2 and 3, between lumbar vertebrae 3 and 4, between lumbar vertebrae 4 and 5, and between lumbar vertebrae 5 and the sacrum are constantly under strain, causing damage. These coincide with most of the most common causes of lower back pain, including herniated discs, spondylolisthesis, intervertebral arthritis, and spinal stenosis.

By spending this time sitting in a simple way that keeps the buttock muscles from relaxing (not pushing up) and stabilizing the pelvis, sacrum, and coccyx (base), you will feel less tired, sit more comfortably, and have a positive effect on your posture (spine). Good posture naturally improves blood flow, which can lead to good health and a rejuvenated appearance.

This invention relates to a seat-type posture corrector and chair-type posture corrector that allows you to sit normally without shortening your gluteal muscles, improving your posture and health. These seat-type posture correctors and chair-type posture correctors can be used for student chairs, office chairs, conference chairs, dining chairs, vehicle chairs, Shinkansen seats, train seats, bus seats, truck seats, sofas, etc.

Once your posture has become bad, it takes years to correct it, but practicing the method of this invention from childhood is the most effective way to improve your posture, and it will bring about both beauty and health. A healthy body will nurture a heart full of love. If children all over the world use the seat-type posture correction device and chair-type posture correction device of this invention, we can spread a rainbow of peace over the world.

The seat-type posture correcting device 1 and chair-type posture correcting device 5 according to the present invention will be described in detail below with reference to the drawings. The seat-type posture correcting device 1 shown in Figs. 1 and 2 has a seat surface that is inclined from the front 2 to the rear 3 and is downwardly inclined. In order to realize the effect of the present invention, the inclination angle when seated is set to be within the range of 1.5 degrees to 8 degrees. Although it varies depending on the condition of the seat, the inclination angle is preferably 1.5 degrees to 6 degrees, more preferably 1.5 degrees to 4 degrees, and particularly preferably 2 degrees to 3 degrees, from the viewpoint of comfort and not feeling fatigue. In the seat-type posture correcting device 1, if the seat surface is inclined 1.5 degrees to 8 degrees downward toward the rear, the user can sit in a way that does not naturally shorten the gluteal muscles.

The seat base plate 5 of the seat type posture correction device 1 is preferably made of a hard material to enhance the effect of the present invention. There is no particular restriction on the material, but wood and hard polyurethane foam are preferable. The seat base plate 5 may be laminated or composite, and there is no problem as long as the outermost layer of the seat base plate 5 is the hard material described above. If it is too hard, there is no problem in attaching a cushion 4 and a cover. Any known cushion 4 and cover can be used.

The chair-type posture correcting device 6 shown in Fig. 3 is a chair equipped with the seat-type posture correcting device 1 described above and a backrest provided behind the seat. More specifically, the chair has the seat 1 and the backrest 7, which are made up of a seat base 5 with an inclination of 1.5 degrees to 8 degrees from the front 2 to the rear 3, and a cushion 4 that can be attached as necessary.

If the seat of the chair-type posture correcting device 6 is inclined backward at an angle within the range of 1.5 degrees to 8 degrees, the user can sit in a position that does not shorten the gluteal muscles naturally by simply sitting on the chair. If a backrest 7 is provided, the angle of the backrest 7 may be set to an angle that maintains the inclination angle of the seat when seated, within the range of 1.5 degrees to 8 degrees. For example, the backrest 7 may be set within 5 degrees forward and 10 degrees rearward from the right angle.
